Modifications in the Interapertural Exine Following Pollinations of Linum grandiflorum

Conference paper


Due to inertness of sporopolienin, the outer exine is one of the most stable biological structures. Changes in the exine following pollination are therefore particularly interesting and thus far have been reported in only three plants: Pharbitis nil (Gherardini and Healey, 1969); Linum grandiflorum(Dickinson and Lewis, 1974) and Ulmus glabra(Rowley. 1983). In Linum grandiflorum degradation of sporopolienin was found to be restricted to the colpal areas.
